For example, age is the ratio, 20 years old than 30 years old young 10 years old, can also ask for the mean value of age.Data types In addition to this classification there are other classifications, but such classification is the basic classification, mastered can be status quo. The quality of the data is mainly: Missing attribute values, object duplication, outliers, inconsistent
